OLED and QLED are two different types of TV technologies that approach producing an image on the screen differently. Here are the key differences between OLED and QLED:

OLED (Organic Light Emitting Diode):

• Each pixel provides its own light source, and the pixels have thin layers of organic material in them, which light up when electricity is applied.
• OLED TVs can generate high-contrast images with truly deep black tones because each individual pixel can go from bright to fully off.
• OLEDs tend to be much thinner and lighter than QLEDs because no backlight is needed.

QLED (Quantum Dot Light Emitting Diode):

• QLEDs are actually a type of liquid crystal display (LCD) with an extra layer that improves the color of the display.
• QLEDs use a quantum dot film to the LCD "sandwich".
• QLEDs start with a blue light source and use quantum-dot material to produce red and green light.
• QLEDs have a higher brightness, longer lifespan, lower price tags, and no risk of burn-in.

In terms of picture quality, OLED beats QLED every time in side-by-side comparison reviews. OLED TVs have better contrast, deeper black levels, and a wider viewing angle, while QLED TVs have a higher brightness and more vibrant colors. However, QLED is the better all-rounder.
